My invention relates to means for feedthe bar 28 on the machine-frame, ting caps, especially, but not restrictedly, .of the screw, as Wlll bereadily undew those having screw-threads, or similar arad ust1ng theposition or elevation of th ticles, so that they may be ap lied to thecap chute. necks of containers, such as ottles, jars As is shown mFigure 5, the ski ingchute co d'th lik comprises a plate bent longituinally to One aim of the invention is the provision provide a lowerportion 41, a vertical abutof a structure of this character, which isment wall 42 and an upper or cover art simple in construction, which canbe pro- 43 d1sposed at an inclination to the ase I0 duced' economicallyand which will aceomsection 41, the latter having mounted there- 6|modate caps of diiferent sizes. on, as by screws or bolts 44, anotherbent Other advantages incident to the invenplate member, shaped toprovide a base 45, tion will become apparent from a consideraan uprightwall 46 of less height than the tion of the following detailedspecification wall 42, and a sloping floor section 47 which of adesirable embodiment thereof which is extends down from the top mar ofwallz 70 illustrated in the accompanying drawings, 46 to the junction ofthe parts 41 and 42. throughout the several views of which like Thus alongitudinal opening or slot is reference characters have been employedto formed betweenthe' lower edge of the vpart designate the same parts;-43 andthe adjacent/portion of the floor 47. v In these dra in The up erpart" of such chute, at one 76 Figure 1 is a ragmentary elevation ofside, is tted with a laterally inclined, the construction; i small,auxiliariy or supplemental chute 48 Figure 2 is a fragmentarycross-section which may be ormed as a part of the plate on line 22ofFigure 1; of which the" sections 45, 46 and 47 consti- 26 Figure 3 isa similar horizontal cross-sectute portions or it may be a separate mem-80 tion on line 33 oiFigure 1; her supported ,in position in anyapproved Figure 4 is an enlarged partial plan view or convenient way. 7r

This screw carries the weight of the chute it enters the open mouth of acap as the 88 and associated parts and imposes it through latter comesalong, it will arrest or stop the 110 igure 7 is a fragmentarylongitudinal It will be perceived that each cap or cover 90 i passage ofsuch cap and succeeding ones until the misplaced one is removed orproperly replaced. a

This detent easily rides over properly positioned caps as indicated inFigure '5.

Near the lower end of the chute, a casting 61 is fixed against the underside thereof and it has an extension 62 square in cross-section,disposed at one side of and lengthwise the chute.

On this part 62 a stationary bent finger 63 is secured, its'endprojecting into a circular or annular groove 64: (Figure 4) in a knurledscrew 65 having complementary right and left-hand thread sections, anend of such screw having a readily accessible knurled lock-nut 66 forretaining the adj usted screw in position against unintentional turningThe oppositely-threaded, spaced sections of the screw extend throughcorrespondingly-threaded holes in ears 67, 67 of a pair of invertedT-shaped brackets 68, v69 slidingly mounted on the supporting-bar 62,

whereby turning of the screw 65 causes the.

two brackets to approach one another or recede from one another, as willbe readily understood, and, in order that they may be retained orsecured fixedly in adjusted relation, each is supplied with a thumbset-screw 71 designed to bear against the outer face of the bar 62 (seeFigures 4 and 6).

. Bracket 69 has a flange 72 and bracket 68 i has a complementary flange78 both designed comes along on to receive and support the caps 51 asthey, during their descent in the chute, pass from the latter, on to thespaced, transverselydisposed flanges 7 2 and 73 and, in order that thecapsmaynot fall down between such flanges. I provide acorrespondingly-sloping plate 74 between them mounted atits upper end byscrews 75 on the extension of the part 45 which projectsbeyond the endsof the plate sections 43, 42 and 47.

As is shownin Figure 4, a curved plate 7 7 is mounted by means of screws78, 78 on the top of the bracket 68, such plate, in some cases:assisting the descending caps in making the right-angle turn.

The lower ends of the two brackets 68 and 69 are supplied withproperly-shaped retaining companion springs 79, 79 which temporarilyprev/enfi further descent of the caps untila-]ar,,bottle or like 81(Figure 6) a conveyor not shown andby engagement therewith pulls theforemost cap out of such delivery chute in opposition to the slight" orlesser retaining action of thetwo springs.

To hold the most advanced cap down in proper position, on the end of asuitablysupported bar 82, adjustable as to position guideby itsretaining screw and thumb-nut 83, I pivot or hinge a plate 84: at 85 andto press this downwardly on to the top of the cap I use a coiled spring86 encircling a rod 87 .hinged at 88 to the top of the plate andslidable through an aperture in a guidebracket 89 the upper end of therod having one or more limiting nuts 91 which restrict the descent ofthe plate, the latter being yieldingly held down to its work by thespring which bears at its opposite ends againsta collar on the rod andagainst the under face of the part 89.

From the above description and associated illustration, it will be seenthat the cap introduced by hand into the entrance chute slides down thelatter into the main chute and glides down this in contact with thewallfl2, occupying or extending out of the longitudinal opening alongone side of the chute, so that the appliance is readily adapted toaccommodate caps of differentsizes.

The caps pass in succession on to the flanges 72 and 7 3 and theintermediate plate 7 4, turn the corner and slide down into contact withthe retaining springs 7 9 from which they are abstracted by the passingjam or bottles with which they automatilimits without departure from theheart and essence of the invention and without the sacrifice of any ofits substantial benefits and advantages.

In witness whereof I have hereunto set my hand and seal. I
